Abstract (en)
[origin: WO2014180679A1] The invention concerns a sheet of glass with high infrared radiation transmission. More specifically, the invention concerns a sheet of glass having a composition that comprises, in an amount expressed as percentages of the total weight of the glass: Si02 55 - 78%, AI2O3 0 - 18%, B2O3 0 - 18%, Na20 0 - 20%, CaO 0 - 15%, MgO 0 - 10%, K2O 0 - 10%, BaO 0 - 5%, Total iron (expressed in the form of Fe2O3) 0.002 - 0.04%, and a chromium content such that: 0.0001% < Cr203 < 0.002%, expressed as percentages of the total weight of the glass. The invention also concerns the use of such a sheet of glass in a device using infrared radiation essentially propagating inside said sheet. Owing to the high infrared radiation transmission of same, the sheet of glass according to the invention can advantageously be used, for example, in a screen, panel or tablet, the sheet of glass defining a touch-sensitive surface.
Abstract (fr)
L'invention concerne une feuille de verre à haute transmission aux rayonnements infrarouges. Plus précisément, l'invention concerne une feuille de verre ayant une composition qui comprend, en une teneur exprimée en pourcentages en poids total de verre :Fer total (exprimé sous forme de Fe<sub>2</sub>O<sub>3</sub>) 0,002 - 0,02%, une teneur en Fe2+ (exprimée sous forme de FeO) inférieure à 20ppm et une teneur en chrome telle que : 0,0001% < Cr2O3 < 0,002%, exprimée en pourcentages en poids total de verre. L'invention concerne également l'utilisation d'une telle feuille de verre dans un dispositif utilisant un rayonnement infrarouge se propageant essentiellement à l'intérieur de ladite feuille. Grâce à sa haute transmission aux rayonnements infrarouges, la feuille de verre selon l'invention peut être avantageusement utilisée, par exemple, dans un écran ou panneau ou tablette, la feuille de verre définissant une surface tactile.
